To get 2 GB space from `/dev/sda9` and add it to `/dev/sda12`,follow the below steps,

You must had to boot from ubuntu live disk.So that all the partitions will be unmounted.And make sure that no one is mounted.
After opening gparted,Right click on the /dev/sda9 partition and select Resize/Move option.Resizing it to get 2 GB unallocated space.It was placed just below to the /dev/sda9 partition.
You need to move the 2 GB unallocated space just below to the /dev/sda12 partition,so that it can be combined with your ubuntu /dev/sda12 partition.
Right click on the sda9,select Resize/Move and move the dragger to the extreme right,so that the unallocated space will be moved just above to the /dev/sda9 partition.
Try the above step to move the unallocated space just above to the linux-swap partition(/dev/sda8).Now both the unallocated space will be combined into one(2 GB+5 MB)
Now right-click on the /dev/sda12 partition and select Resize/Move option.Now you can be able to add the unallocated space to the /dev/sda12 partition.
